Improvement in boot-crimping machines



NITED STATES HORACE WING, OF BUFFALO, NEW YORK.

IMPROVEMENT IN BOOT-CRIMPING MACHINES.

Specification forming part of Letters Patent No. 42,324, dated April l2, 1864.

T0 0,55 whom it may concern,.-

Be it known that 1, HORACE WING, of the city of Buffalo, county of Erie and State of New York, have invented an Improved Boot-Crimping Machine; and I do hereby declare that the following is a full and exact description of the construction and operation thereof', reference being made to the accompanying drawings, ma king a part ot' this speci iication, in which- Figure I is a side elevation of my improved machine. Fig. ll is a plan.

This invention relates to an improvement inthe construction and operation oi the crimp ingplate in machines for crimping leather, and is an improvement upon my patent of July 31, 1800.

A represents the case or bed of the machine, which is supported upon the legs B.

O represents the crimping-jaws, composed of two plates, which stand upon the bed and project upward therefrom, and are held to the bed by means ota screw through each plate, one ot' which is shown at C. The screw which holds the plate forming one-half ot' the jaw, and which is opposite to that shown in Fig. I, is loosely tilted, so as to allow that half of thejaw to rock or move suiiiciently to accommodate the jaws to different qualities of leather and to the various stages ot' the leather during the crimping process. These jaws are opened and closed by means of the screw-bolt D', which bolt passes through a hub made in thejaws and crank-nut E on the end of said bolt, substantially as described in my patent of July 31, 1860, to which reference may be had.

The crimping-plate is represented at F. It differs from all other crimpingplates heretofore made in the fact that its front end is left open and unobstructed, so that any length ot' bootleg may be crimped without the slightest impediment. It is hinged to a short slotted post, G, by'means of the bolt H, which bolt becomes a tulcrum to the plate. It has a rear projection, G', on the extreme edge of which is a gear-segment, I, which segment meshes in with another gear-segment,` J, supported on an appropriate shaft or fulcrum-holt, J', on the top ot' the post K. The posts Gr and K are connected with and project from the bed A. A socket., L, projects from the gear-segment J for the reception of the end of the operatinglevcr L', so that by means of the operating-lever and the gear-segments a great purchase or leverage is obtained ou the crimping plate, and a sufficient sweep is obtained on its front or open end by a slight movement ot` its rear or segment end. and all the required movements may be given with great facility.

M is a brace extending from the post G to the post K. There are two braces of this kind, one 011 each side. The fulcrum-bolts H and J pass through their ends, as represented in Fig. I. Y

rIhe clamp for holding the leather to tIe crimping-plate is shown at N, and the screw for operating the clamplis shown at S. These parts are constructed and operated substanstially as described in my patentof July 31,

What I claim as my invention, and desire to secure by Letters Patent, is-

A crimping-plate, F, so constructed as to leave its frontend open or free and unobstructed, and operated upon a fulcrum-bolt, H, by gear-segments I and J, substantially as described.
